Abstract

This paper presents a generic and simple transformation that adds traceability to an anonymous encryption scheme. We focus on the case of honest senders, which finds applications in many real-life scenarios. Advantageously, our transformation can be applied to already deployed public-key infrastructures. Two concrete implementations are provided.
